Line head chassis detachably attaching jig in an inkjet recording apparatus

Abstract

To make a line head chassis detachable simply and easily in an inkjet recording apparatus, a jig for the line head chassis is provided which comprises: a first support member mounted on a table lateral to the inkjet head; a second support member mounted laterally to and lower than the first support member; a rail member mounted laterally to the first support member and having one end connected thereto; an upright support member having its lower end supported by the second support member adjustably in its height direction and its upper end connected to the other end of the rail member for supporting the rail member horizontally; a base table slidably supported on the rail member to move over a distance outward from a maintenance position; and a cradle means supported on the base table so as to be movable perpendicularly to a direction in which the base table moves for accepting the line head chassis, wherein one end of the rail member and the lower end of the upright support member are made engageable with/disengageable from the first and second support members, respectively.

1. In an inkjet recording apparatus having an inkjet head comprising a controller housing that can be moved between a printing position and a maintenance position lateral to the printing position and a line head chassis that can be attached to and detached from the controller housing, a jig for the line head chassis characterized in that the jig comprises a first support member mounted on a table lateral to the inkjet head; a second support member mounted laterally to and lower than said first support member; a rail member mounted laterally to said first support member and having one end connected thereto; an upright support member having its lower end supported by said second support member adjustably in its height direction and its upper end connected to the other end of said rail member for supporting said rail member horizontally; a base table slidably supported on said rail member to move over a distance outward from said maintenance position; and a cradle means supported on said base table so as to be movable perpendicularly to a direction in which said base table moves for accepting the line head chassis, wherein one end of said rail member and the lower end of said upright support member are made engageable with/disengageable from, said first and second support members, respectively. 
   
   
     2. A jig for the line head chassis in an inkjet recording apparatus as set forth in  claim 1 , characterized in that a head catch tray for accepting said line head chassis is mounted on said cradle means so that it can be engaged with and disengaged from the latter.
